Device for noncontact monitoring the technical condition and operation mode ELECTRICAL

摘要

The invention relates to the field of test and measurement equipment and may be used for automated control of the contactless technical state and modes of AC electric various purposes. The device is designed as a two-wire cord extension cable which connects between the controlled electrical installation and electric network, thus it introduced differential transformer, two primary windings of which are formed from both cores apex extension bifilar and the secondary winding is connected to an information processing apparatus, in addition from one core two-wire cable forming the winding current which is placed inside the magnetic field sensor, whose output, in turn, connected to the processing device information connected to the display unit.
